WHY does adding more loads in a parallel circuit increase the current?

Adding more loads in a parallel circuit increases the current because of Kirchoff's voltage and current laws, and because of Ohm's law...
1. Kirchoff's voltage law states that the signed sum of the voltage drops around a series circuit is zero. A consequence of this is that the voltages across elements of a parallel circuit must be the same.
2. Ohm's law states that current is voltage divided by resistance. Since the voltage across each new parallel element is the same, the current in that element is known. A consequence of this is that each additional element does not change the current in the other elements.
3. Kirchoff's current law states that the signed sum of the currents entering a node is zero. A consequence of this, and 1 and 2 above, is that the currents added by each parallel element increases the total current entering the set of parallel elements.

Discuss why adding a resistor in parallel to an existing circuit increases the total electric current in the circuit?
V=IRyou are adding in parallel, so V is non-zero, because R is positive, I must have the same sign as V. Therefore your current will increase.
How does increasing the number of cells in a parallel circuit affect the current?
by adding resistance in parallel more current is bound to flow
What will happen to the total current if you keep adding bulbs in parallel to the circuit?
Adding more lamps in parallel (across) a line will cause total current to climb. It will keep climbing (increasing) until a load protection device (circuit breaker or fuse) breaks the circuit or until something fails because of excessive current.
In a parallel circuit adding more bulbs will increase?
It will decrease the effective load resistance across the power supply terminals, increase the total current through the load, and increase the total power required to be supplied by the power supply.
What happens to the overall resistance of a circuit when too many appliances are connected across a 120 V outlet?
This is a very technical electrical question that may be difficult to understand without further study. But adding appliances to an outlet is the same as adding resistance in parallel. Adding resistance in parallel, the resistance of the circuit goes down. That is why you get more current flow. By contrast, adding resistance in series increases the resistance of the circuit and therefore reduces current, all else being equal.

How do you increase current?
Current can be increased by adding a larger load to the circuit.

When you short out a resistor in a parallel circuit why does the current lower?
The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total. By removing a resistor the total current will lower. If you short out the parallel circuit as suggested it will take out the fuse that should be protecting the circuit.AnswerShorting-out a resistor in a parallel circuit, will act to short out the entire circuit, therefore, significantly increasing, not lowering, the current! And, as the previous answer indicates, this short-circuit current will operate any protective devices, such as a fuse.In a parallel circuit current does not lower but it will be increase if shorting-out one resistor in the two resistor parallel circuit, the circuit will become very low resistive and the larger current will flow through the short path.

What would be the effect of adding a load in parallel to a parallel circuit?
Ohm's Law says Voltage = Current x Resistance With constant voltage, an increase in resistance decreases the current. Now the load can be added in two basic ways. If the load is added in series the resistance will increase. If you add load in parallel the resistance will decrease and the current will increase from the source.
Why does adding more appliances to a circuit increase the current?
More appliances means more load are being added, which necessariliy increases the current.
Does power decrease when adding resistors in parallel circuit?
no
In a series circuit what happens to the current if you increase the number of components in the circuit?
The current (amps) will remain constant, but the voltage will drop.

Why is circuit current reduced when a capacitors added to the circuit?
In the case of an a.c. circuit, capacitors oppose current because of their capactive reactance, expressed in ohms. Capacitive reactance is inversely-proportional to the capacitance of the capactor and to the frequency of the supply. So, adding a capacitor is series with an existing load will reduce the load current. On the other hand, adding a capacitor in parallel with an existing load will decrease the load current.
